| Total Cost of Ownership | Higher due to downtime | Lower through longevity & reliability |
Cryogenic valves use specialized materials and an extended bonnet to prevent the packing from freezing and to ensure the stem remains operable at temperatures as low as -196℃.
For LNG, we typically use ASTM A351 CF8M or CF3M (Stainless Steel) and spring-energized PCTFE seats to maintain seal integrity in cryogenic temperatures.
Yes, our valves are designed and manufactured according to API 6D, ASME B16.34, and BS 6364 to ensure global compliance and safety.
In cryogenic conditions, materials contract. The spring energizer maintains constant pressure on the seal, ensuring a bubble-tight shut-off despite thermal contraction.
Every valve undergoes 100% hydraulic shell and seal testing, low-pressure air tests, and non-destructive testing (DPT) to ensure zero defects.
We provide a minimum service life guarantee of 12 months, including free spare parts and professional technical support for non-human induced damage.
